【摘要】：礦井通風(fēng)系統(tǒng)作為礦井生產(chǎn)的一部分,其優(yōu)良性決定著礦井能否正常有序地生產(chǎn)。在老廠錫礦新區(qū)通風(fēng)系統(tǒng)中,現(xiàn)有的通風(fēng)系統(tǒng)有兩個(gè)回風(fēng)系統(tǒng),而其中期北山回風(fēng)井巷回風(fēng)風(fēng)量大而斷面面積較小,按金屬礦非金屬礦安全規(guī)程中專用回風(fēng)井的風(fēng)速限定,礦井的最大通風(fēng)量遠(yuǎn)小于為滿足現(xiàn)礦井生產(chǎn)所需的風(fēng)量,故需要對(duì)老廠錫礦新區(qū)礦井通風(fēng)系統(tǒng)進(jìn)行優(yōu)化改造。 本文在查閱大量相關(guān)文獻(xiàn)后,結(jié)合老廠錫礦新區(qū)通風(fēng)系統(tǒng)的實(shí)際情況提出兩大通風(fēng)系統(tǒng)改造方向：一是將制約通風(fēng)能力的期北山回風(fēng)井巷進(jìn)行擴(kuò)刷,二是在合適的地表位置新建一條回風(fēng)井連接原礦井。而兩類通風(fēng)系統(tǒng)改造都涉及到井巷的最優(yōu)斷面問題,為盡量減少對(duì)礦井現(xiàn)有生產(chǎn)的影響和考慮到影響通風(fēng)壓力損失的主要部分,在本礦井通風(fēng)系統(tǒng)中僅對(duì)風(fēng)量集中的回風(fēng)井巷部分進(jìn)行改造。 在兩大通風(fēng)系統(tǒng)改造方向的基礎(chǔ)上,結(jié)合相應(yīng)的礦井通風(fēng)系統(tǒng)特點(diǎn),分別建立多風(fēng)機(jī)多級(jí)機(jī)站通風(fēng)系統(tǒng),在3Dvent通風(fēng)解算軟件的分析幫助下提出多個(gè)合理、可行的礦井通風(fēng)系統(tǒng)方案,在不同的通風(fēng)系統(tǒng)方案中已用3Dvent通風(fēng)解算軟件的風(fēng)機(jī)庫對(duì)其主要通風(fēng)機(jī)工況點(diǎn)進(jìn)行優(yōu)化,并對(duì)每種方案進(jìn)行了通風(fēng)網(wǎng)絡(luò)解算。最后本文根據(jù)前人的研究成果和本礦井特點(diǎn)建立了一套較為科學(xué)、全面的通風(fēng)系統(tǒng)評(píng)價(jià)指標(biāo)體系,結(jié)合層次分析法和熵技術(shù)法給各評(píng)價(jià)指標(biāo)賦權(quán)值,再運(yùn)用計(jì)分法選出最優(yōu)通風(fēng)系統(tǒng)方案。 本文通過對(duì)老廠錫礦新區(qū)礦井通風(fēng)系統(tǒng)的現(xiàn)狀分析和大量相關(guān)文獻(xiàn)的研究,提出了通風(fēng)系統(tǒng)改造方向,在給出的多個(gè)通風(fēng)方案中選擇出最優(yōu)通風(fēng)系統(tǒng)方案,指導(dǎo)礦井實(shí)際工作,帶來了一定的經(jīng)濟(jì)效益,同時(shí)也為其它礦井通風(fēng)系統(tǒng)優(yōu)化工作供一定的參考作用。
[Abstract]:As a part of mine production, mine ventilation system determines whether the mine can produce normally and orderly. In the ventilation system of Laochang Tin Mine New area, the existing ventilation system has two return air systems, but in the middle period of the Beishan return air shaft, the return air volume is large and the cross section area is relatively small, which is limited by the wind speed of the special return air well in the safety regulations for non-metallic ore mines. The maximum ventilation volume of mine is far less than that needed to meet the needs of present mine production, so it is necessary to optimize the ventilation system of the mine in the new area of Laochang Tin Mine. After consulting a large number of relevant documents, combined with the actual situation of ventilation system in the new area of Laochang Tin Mine, this paper puts forward two major directions of ventilation system reform: first, the ventilation capacity of Beishan return air shaft and roadway in the period of restricting ventilation capacity is expanded. The second is to build a return air shaft to connect the original mine at a suitable surface position. In order to minimize the impact on existing mine production and to consider the main part affecting ventilation pressure loss, both types of ventilation systems are related to the optimal section of the shaft and roadway. In this mine ventilation system, only the return air shaft with concentrated air volume is reformed. On the basis of the reform direction of two ventilation systems, combined with the characteristics of mine ventilation system, the ventilation system of multi-fan and multi-stage machine station is established separately. With the help of the analysis of 3Dvent ventilation calculation software, several reasonable ventilation systems are put forward. In different ventilation system schemes, the main ventilator operating points of 3Dvent ventilation solution software have been optimized, and each scheme has been calculated by ventilation network. Finally, according to the previous research results and the characteristics of this mine, a set of scientific and comprehensive evaluation index system of ventilation system is established, and the weight of each evaluation index is given by combining the analytic hierarchy process (AHP) and entropy technique. Then the optimal ventilation system scheme is selected by using the scorecard method. Based on the analysis of the present situation of mine ventilation system in Laochang Tin Mine New area and the study of a large number of related documents, this paper puts forward the reform direction of ventilation system, and selects the optimal ventilation system scheme among the several ventilation schemes given to guide the actual work of the mine. It brings some economic benefits and provides some reference for other mine ventilation system optimization.
